In some far north places, the sun you do get is not strong enough to get any Vit D. http://web.archive.org/web/20210302053343/https://jaoa.org/article.aspx?articleid=2635300 http://web.archive.org/web/20210302053343/https://jaoa.org/a... https://www.grassrootshealth.net/document/sunshine-calendar/ https://www.grassrootshealth.net/document/sunshine-calendar/

Indeed, the UK which is further north than the majority of Canada's population has effective vitamin D from the Sun only from March to September. Spring Equinox to autumn equinox basically. The sun is too low even though it might be much warmer than lower latitudes!

  Yurp. I live in the south of England and even here I take vit D for pretty much that time period or I end up with little to no energy. I always make sure to go outside as much as I can, but when the sun is coming up at 8am and has gone down by 6pm it's pretty hard to get enough daylight and also work.

    Worse in Edinburgh. Sunset is at 4pm for god's sake.

In the Southern Hemisphere (yes, people do live south of the equator) this advice is complicated by the ozone hole causing the risk of skin cancer to be much higher than in the northern hemisphere.
